September is my favorite time of year to fish in Central Oregon. Anglers are spoiled for choice and blessed with better conditions as the fall bite kicks in—right as kids head back to school. It’s the stretch of the season I look forward to most, and here’s why.
September Is Prime Fishing Season
You can’t beat September weather for fishing. Temperatures begin to cool, water stays clear, and the days are still long enough for a full outing. As fall storms roll in, we’re finally treated to overcast skies after months of blinding sun. These storms are a blessing—fish often gorge themselves during the sudden pressure drops before the wind picks up.
By September, trout seem fully recovered from the stress and blinding rays of summer. Cooler water holds more oxygen, and with winter looming, fish are eager to fatten up before bug life slows down. Hatches thrive this time of year: more mayfly activity, the first hints of October Caddis, the annual appearance of Fall Green Drakes, and even some small stoneflies.
The Waters We Fish in September
The Deschutes River
The Deschutes is my top September river. Big redband trout paired with steelhead on the swing make for unforgettable days. I wait all year for steelheading here—September is when catch rates pick up. Fish move from the lowest reaches of the canyon, over Sherar’s Falls, and spread through the system. By October, action runs from the mouth all the way up to Pelton Dam. Quick tip: resident trout rarely key in on October Caddis. Rather, steelhead dry flies that mimic October Caddis tend to be quite effective for a couple of weeks.
The Crooked River
The Crooked settles into reliable shape in September. While flows are often at the mercy of dam regulators, fall usually brings stability. Hatch activity is steady, with plenty of midges and mayflies. The evenings are still bright, making for great after-work sessions when the bugs pop.
The Metolius River
The Metolius in September is pure fun. Local anglers await the annual Fall Green Drake hatch – a fleeting thrill. These large mayflies need optimal conditions to hatch, but when the stars align the trout go on a brief feeding frenzy. This is also kokanee migration season, and big bull trout follow, feeding on eggs and even the kokanee themselves. It’s the perfect time to put away the white-colored staples and swing large red and olive streamers. I like to break out my switch rod to throw the heavy stuff in tight quarters like the Met.
The Lakes
Don’t overlook the lakes. As fall sets in, dry fly action returns on overcast days, and trout feed heavily before ice forms. Streamers work well, especially in waters with browns, brookies, and tiger trout. Cooler temps push fish into the shallows, spreading them out and making them more accessible to bank anglers.
September Fishing Considerations
- Dress in layers: Cold mornings and warm afternoons call for thin, stowable layers. A light rain jacket or windbreaker is always worth packing. Bring your waders along too.
- Be versatile: Hatches are strongest mornings and evenings, so bring both dry flies and nymph rigs to stay productive through midday.
- Watch the weather: Overcast skies and pre-storm conditions often mean lights-out fishing. The trade off is that you might need to prepare to fish in howling afternoon winds.
Closing Thoughts
September is a special time for Central Oregon anglers. Get out while conditions are prime, and don’t miss the chance to experience some of the year’s best fishing. Winter will be here soon enough, but for now, enjoy every cast in these crisp fall days.
